...into syntax-highlighted HTML that I can't really usefully represent here. It uses Text::VimColor, so you can read more about the kind of HTML it will produce, there. The parameter after "=begin vim" is used as the filetype.

This form is also accepted, in a verbatim paragraph:

#!vim lisp
(map (stuff (lisp-has-lots-of '(,parens right))))

In the above example, the shebang-like line will be stripped. The filetype parameter is mandatory.

The format_name attribute may be supplied during the construction of the transformer to look for a region other than vim.
